Hello, i'm new to RDX and it seems really cool, but for some reason I can't move or remove abilities on my action bars. Am I missing something?

I checked the Blizz UI options and they are not locked there, is there another option in RDX that locks your abilities?

edit: Also, I noticed that there is a slight inset for all the actionbar icons, removing the border on the icon itself. I use Clean Icons to maintain a consistent look but the thin border is now gone. Is this a part of the base RDX or the button skin? Is there anyway to disable/remove the offset?
